I customised chiller performance curves of Chiller:Electric:EIR
based on manufacturer's technical data.
I think the description of Electric Input to Cooling Output Ratio Function of Part Load Ratio Curve Name in I/O Reference is incorrect. I/O Reference says that "This curve is generated by dividing the operating electric input power by the available full-load capacity (do not divide by load) at the specific operating temperatures.", but I think the curve should be generated by dividing the operating electric input power by the rated electric input power.
I think the description in Engineering Reference is correct.
Pleaese correct me if I'm wrong.
